FEniCS 1.2.0 installation on Mac 10.8.3

Question

I just downloaded the binary version of FEniCS 1.2.0 on Mac 10.8.3. I updated my OS and installed Xcode and X11 Libraries. When I ran "python demo_poisson.py", it gave me the following error. Any suggestions on how to fix it?

Calling DOLFIN just-in-time (JIT) compiler, this may take some time.
In instant.recompile: The module did not compile with command 'make VERBOSE=1 ', see '/Users/xpqian/.instant/error/dolfin_compile_code_f6c3010fb014663578b3cbc5ec745210/compile.log'

I opened the "compile.log" and saw the following error message.

Comments

Could you add one of the long failing link lines that you have outcommented?

Are you compiling with gcc? It looks like the JIT compiler cannot find libgomp, which is an openmp implementation for gcc. Is that library installed and if so where?

I added the long link line in the question above.

I used "python demo_poisson.py", which may have triggered gcc.

How do I verify if libgomp is installed?

I had problems to get fenics running on a fresh OS X 10.8.5 installation. I had to install the command line tools in the preferences of XCode. Then everything worked fine.
